Couch Wall Spacer (Bob's Libre 2)

I made this to keep my couch from being pushed into the wall (AC inlet vent is right behind the couch). This is made for the Bob's Libre 2 Couch (https://www.mybobs.com/living-room-furniture/living-room-sets/libre-ii-2-piece-left-arm-facing-sectional), though it could probably be adapted for other couches.
